Fossil fuels, above all coal, continue to dominate the Czech Republic's energy and power generation mix. However, EU climate targets are making coal increasingly unattractive as an energy supplier. Phasing out power generation from coal and switching to sustainable, renewable energy sources are the main challenges facing the Czech energy sector. Although the share of renewables in the Czech energy mix has increased significantly in recent years, they still play a minor role. In 2019, just 16% of the country's total final energy consumption came from renewable energy sources, mainly bioenergy.
